Interactive terminal sessions

[beriberikix]

An interactive terminal session seems to be out of scope today but a lot of implementation that already exists for interactive snippets is in place that could make it feasible in the future. My use case is when a developer is learning framework that first needs to be compiled and then needs to be interacted with from the terminal. The closest example of interactive terminal akin to this is https://termible.io/, which was a service that never launched. https://github.com/yudai/gotty is another example. My dream solution is codapi + termible.

It's possible to simulate terminal interaction today but it's obviously not a intended use case. I've hacked together something that combines multiple steps on the server and clunky use of code cells/depends-on on the client.
